Nakai were analyzed. For all 9 characters, there were no significant differences existed within mother trees, however, there were significant differences existed among sources and trees with the coefficients of variation vary from 13.39% to 36.43%. The order of the variation degree is among sources>among mother trees>within mother trees. Drupe size and shape were closely related with those of seed, but the pulp production ratio was not related with other characters.展开更多
